As a newly hired senior C++ developer with experience in gtkmm, you are tasked with performing essential steps in the GTK4 migration for Inkscape. You must ensure that the C++ bindings (gtkmm, pangomm, cairomm, etc.) are adequate over a four-month period. Working closely with an Inkscape expert, together, you will form a powerful team to drive the migration of hundreds of files in the codebase as quickly and efficiently as possible.
